VAPOR-LAMP.

SPECIFICATION forming part of Letters Patent No. 766,179, dated August 2, 1904.

Application filed December 28 1903. Serial No. 186,877. (No model.)

T0 all wiz/0ml t party concern:

Be itknown that I, ABRAM GLovEE,a citizen of the United States, residing at Riflein the county of Garfield and State of Colorado, have invented a new and useful Vapor-Lamp, of which the following is a specification.

This invention relates to vapor-lamps, and more particularly to that type of vapor-lamps in which the vapor is formed by passing' a liquid hydrocarbon fuel of suitable density through a heated generator-tube.

The object of the invention is to provide in a vapor-lamp of the type specified improved means for imparting to the generator-tube the heat necessary to effect the initial vaporization of the liquid fuel passing through the generator-tube and to provide simple means for cleaning the generator-tube by permitting the contents thereof to flow out without interfering with the adjustment of the parts of the lamp.

In attaining the object above mentioned and others which will appear as the invention is more fully disclosed I make use of the novel construction and combination of elements hereinafter fully described, illustrated in the preferred form of embodiment in the accompanying drawings, forming a part of this specification, and havingl the novel features thereof specifically pointed out in the appended claims, it being' understood that changes in the form, proportions, and exact manner of arrangement of the elements of the structure disclosed may be resorted to without departing from the spirit of the invention or sacrificing its advantages.

In the drawings, Figure 1 is a View, partly in elevation and partly in section, looking toward the generator-arch from one side, one of the mantles and burner-tubes being removed to expose the structures between the two mantles. Fig. 2 is a view in elevation taken from the left of Fig. 1 and showing all the essential parts of a lamp of the type to which the invention relates.

Referring to the drawings, in which corresponding parts are designated by similar characters of reference, 1 designates the generator, which in the form of vapor-lamp illustrated is atube of comparatively small diamprovided a coupling' 5 for attachment to a supply-pipe 6, and at the end of the shorter leg' l an angular member 7, comprising a horizontal portion 8 and a vertical portion 9, is rigidly attached to the generator-tube. The member 7 is hollow, as shown in Fig. 1, and the horizontal portion 8 thereof, which constitutes the vapor-valve nozzle, is provided at one end with a cap 10, threaded on said horizontal portion and containing the stem 11 of a needle-valve. The pointed end of the stem cooperates with a conical seat 12 in the outer end of the horizontal portion or vapor-valve nozzle 8 of the member 7 to control the escape of vapor through a very small opening' 13 at the apex of the conical seat. The lower end of the vertical portion 9 of the member 7 is closed by a cap 14, threaded thereon, and the stem 15 of a needle-valve is mounted in said cap. The sharpened end of the stem 15 cooperates with a conical seat 16 to control the passage of liquid hydrocarbon through a small opening' 17 at the apex of the conical seat, whence the hydrocarbon flows through a lateral branch tube 19, which extends at right angles from the vertical portion 9 of the member 7. An extension 2O from the tube 19 is carried upward and around the cap 10 and terminates in a horizontal dischargingtip 21, which directs a slender stream of liquid hydrocarbon upon a mass of asbestos Q2, supported in any suitable manner adjacent to the end of the extension 20.

The valve-stem 11. is preferably provided on the outer end thereof with a cross-bar 23, which is rigidly attached to the valve-stein and is provided at its ends with chains 24, which hang downward and afford convenient means for giving the valve-stem 11 a partial IOO moment.

rotation to open or close the needle-valve, by which the escape of gas through the opening 13 is regulated.

A shield 25 is preferably mountedV on the outer end of the horizontal portion 8 of the member 7, and an air-mixing tube of any suitable form is supported adjacent to the shield in front of the opening 13, so that the gas escaping through said opening will pass directly into the air-mixing tube, drawing with it a suitable quantity of air to mix therewith and form an explosive mixture capable of burning without additional supply of air. In the form of lamp illustrated the air-mixing tube is shown at 26 and consists of a piece of tubing of considerably larger diameter than the generator-tube, which extends downward in a curve to a point beneath the cap 10 and then extends upward to supply the mixture of air and vapor to the burners. In the embodiment of the invention illustrated the air-mixing tube communicates with a horizontal tube 27, from which extend upward two burner-tubes 28, arranged on opposite sides of the cap 104 and supplying iiame to heat two mantles 29, arranged upon opposite sides of the arch 2 of the generatorl and supported in'any suitable manner.

rIhe operation of the lamp above described is as follows: Both of the needle-valves being closed and the generator-tube being filled with hydrocarbon-liquid fuel, the valve-stem 15 is turned sufciently to allow the liquid to flow through the branch tube 19 and the extension 20 attached thereto, being discharged upon the asbestos 22 at the end of the tube 19. rIhis fuel being ignited by a match or any other preferred igniting device, a flame is directed upon the generator-tube, striking the bends 3a and 4: and the portion of the generator-tube between these bends. The heat imparted to the tube will soon raise its temperature sufficiently to cause the liquid contained therein to be converted into vapor, and the vapor so produced will begin to escape through the tip 21 of the tube 20, giving rise to a flame of different character from that produced by burning the liquid hydrocarbon. When this takes place, the valve-stem 11 will be turned, allowing the vapor to escape through the small opening 13 and pass into the air-mixing tube 26,where it becomes mixed with air and passes on to feed the burners by which the mantles 29 are heated. The mixture of gas and Vapor rising through the burner-tubes 28 is ignited by the flame from the tube 20, and the mantles become heated to incandescence in a The valve-stem 15 may then be turned to close the valve and cut off the iow of vapor through the tubes 19 and 20, and the vaporization of the hydrocarbon liquid in the generator-tube will be continued by the heat imparted to the generator from the incandescent mantles arranged on opposite sides thereof.

From the foregoing description and the Vdrawings illustrative thereof it will be seen that the delay in setting the lamp in operation is reduced to a minimum and that the tubes 19 and 20, by which liquid fuel is vsupplied to the asbestos to effect the initial heating of the generator, afford means for cleaning the generator-tube at any time by merely opening the valve controlling the flow of liquid through the tube 19 to sufficient extent to permit the liquid in the generator-tube to flow freely therethrough.

While I have described the invention as embodied in a lamp of the Doran type, it will be obvious that it may be applied to other forms of lamp in which the liquid fuel is vaporized by passing throughaheated generatortube of similar construction and the vapor allowed to pass from the generator-tube into the mixing-tube.

Having thus described the construction and operation of my invention, what I claim as new, and desire to secure by Letters Patent,

1. In a vapor-lamp, a generator consisting of a tube bent to form an arch having the sid es thereof drawn close together near the bottom of the arch, and a branch tube discharging beneath the arch below the point at which the sides of the arch are drawn together.

In a vapor-lamp, a vertically-arched generator-tube having the sides thereof drawn together near the bottom, a branch pipe extending from said generator-tube near its discharge end and having its terminal disposed beneath the arch of the generator-tube, and a mass of absorbent material disposed adjacent to the terminal of said branch tube and below the point at which the sides of the arch of the generator-tube are drawn together.

3. In a vapor-lamp, a generator consisting of a tube bent to form] an arch having the sides thereof drawn close together near the bottom of the arch, a branch pipe near the outlet of said generator-tube, valves for controlling the flow of fluid through the generator-tube and through the branch pipe, a vapor-valve nozzle disposed transversely upon the generator tube, a needle-valve seated therein, a curved mixing-tube having its inlet disposed in front of the vapor-valve nozzle, a disk supported upon the latterrat a distance from the inlet of themixing-tube, and burnersupporting branches formed upon the latter.

4. In a vapor-lamp, a vertical arched generator-tube, a vapor-valve nozzle near the outlet of said generator-tube, valves for controlling the flow of fluid through the generatortube and through the vapor-nozzle, a curved mixing-tube having its inlet disposed in front of the vapor-nozzle, said mixing-tube having burner-supporting branches, a branch pipe extending from the generator-tube near its discharge end and having its terminal disposed beneath the arch of the generator-tube,

1roV 5 the generator-tube, and means for conveying the fluid from the latter to the absorbent Inaterial.

In testimony that I claim the foregoing as my own I have hereto al'lixed my signature in the presence or' two witnesses.
